packets for the market in one continuous operation.

The class of paper bags which it is intended to manufacture is that formed with a square end, such as used by grocers and dry-goods men.

The paper to form the bag, having been cut into blanks of the required size, is placed on a rising and falling table. Vertical motion is given to this table by means of a cam on the main shaft of the machine acting upon a lever which is connected with a rod pendent from the under side of the table. This table is provided with means for holding down the paper blanks while certain portions thereof which are to form the closed end of the bag receive a supply of adhesive substance from a pair of reservoirs placed above the table and mounted on the ends of rock-levers which are actuated by a grooved cam on the cam-shaft. The paper blank thus prepared is taken up by a-pueumatic holder and placed upon a second table, which is moved forward to receive it. This table, which is open inthe center and forms one end of a rectangular frame, is connected, through an arrangement of levers, with the pneumatic holder, and by its forward motion cli'ects the movement of the latter with the paper blank. The second table, bearing the paper blank, is then drawn back to its original position, during which operation the pa per receives along the edge of one side a supply of adhesive material from a third reservoir fixed in any suitable manner above the table. The reciprocating motion of the table and frame is caused by a rock-lever connected in any suitable manner with the frame and with a special cam on the main shaft. The

paper blank is by this time brought under a horizontal rectangular metal block former or mold with square ends fixed above the table and below this block, and coincident therewith, is a plunger, which is caused to rise by the action of a cam on the main shaft through the opening in the table and raise the blank and hold it against the under side of the mold. In connection with the plunger is a pair of rollers, which, rising with the plunger, press the paper against the vertical sides of the mold. These rollers are each provided with a feather or tappet, and are so arranged that as they arrive at the'top of the mold the feathers or tappets shall bend inward first one side and then the other of the paper which projects above the top of the mold. A finger also rises with the rollers, and, pressing up one end of the blank against the end of the mold, forms the first foldin the bottom of the bag. Following the action of the pressing-rolls, a presserbar descends and completes the folding over of the blank and thejoining of the folds to form the top side of the bag. Connected with this presser-har is a second finger, which, as it descends, forms the second fold in the bottom of the bag.

It now only remains to complete the bottom of the bag by folding the remaining two sides. This is effected by an arrangement'of presserblock and fingers or tappets carried by the rectangular frame above mentioned, and advancin g with this latter. These fingers or tappets, are so arranged that they shall fold down, one after the other, the two remaining sides, to complete the bottom of the bag. The presser-block then presses on these parts, which, by reason of the adhesive substance with which they were supplied at an earlier stage, firmly adhere together. The manufacture of the bag being now completed, it is drawn off the mold by a pair ofspring-clips connected with the presser-block, and is allowed to drop into a box previous to its being deposited on a table below, where it is to be rolled flat for convenience of packing. This box is carried in end bearings, and can be rotated on its axis by means of a rack and pinion, so as to place the bag on the table below, with the joint of the paper downward. This motion of the box is caused by the rising and fallin g of a bell-crank lever to which the rack is connected, the motion of the bell-crank lever being regulated by a cam on the main shaft.

The compressing mechanism consists of a amount of horizontal rollin g motion being regulated by a slot in the end of a lever pivoted to the main frame of the machine. The bag is compressed from the mouth toward the bottom, and the bottom is folded down by a folding blade or plate mounted in asuitable bearmg and actuated by a tail-piece connected with the pendent bracket. The bag thus flattened is passed between squeezing-rollers, and is discharged therefrom into a receptacle consisting of a circular box divided into any de sired number of compartments to hold any desired number of bags, and mounted on a vertical axis, to which intermittent rotary motion is communicated by means of a pawl and ratch et-wheel actuated in any convenient manner from the main shaft. This arrangement of machinery admits of four bags being in the course of manufacture at one time.

In the accompanying drawings, Figure l. is a longitudinal section of the whole of the machine for making paper bags, showing the movements of the various parts. Fig. 2 is an end view upon a larger scale. Fig. 3 is a longitudinal section of a portion of the machine, showing parts thereof in a second position upon a larger scale than Fig. 1. Figs. 4, 5, and .5 show detached views of parts of the machine; and Fig. 6 represents a portion of a sheet of paper for forming the bag, showing the gummed portions; and Figs. 7 to 13 are detached views of the various parts of the apparatus, to be more fully described hereinafter. Figs. A, A,B,B are detail views upon a larger scale than Fig. 1, illustrating the action of the pneumaticholder and the devices for elevating the paper-carryin g table; and Fig. 1*,1", 3 3 are detail views upon a larger scale than Fig. 1, illustrating the devices for removing the bags from the former and flattening and delivering them into the compartments of a circular rotary box or receptacle.

In the different figures the same letters of reference refer to corresponding parts.

The various parts of themachine are mounted on a frame composed of standards A, longitudinal pieces 13, and transverse pieces 0, all securely connected together in any convenient manner.

In describing the various movements and the working'parts it will be most convenient to take them in the order in which the manufacture of the various parts of the bag is carried on.

The paper is first cut into sheets of the dimension required, and the sheets are laid in a pile, a, on the table a, which is provided with side guides, a a and a stop, a, to maintain them in place. The table a is capable of receiving a vertical motion, which raises the paper to or withdraws it from stops (1 a fixed on the frame of the machine, and the top sheet of the paper is taken up when the table is lowered by a pneumatic apparatus, to be hereinafter described. The table a is carried on the end of a rod, d, which is surrounded by aspring, (Z and inclosed in a tube, 61, which slides in the tube d*, which is fixed to the frame in any convenient manner. The lower end of the. rod d projects from the tube d" and enters a fork, N, in the end of a lever, 12, where it is griped between the piece 0 and counterweighted piece 0, both pivoted in the fork. The lever b is pivoted to the frame at b, and it is provided with a hook, D which rests on a cam, 3, by which the lever bis raised and lowered. When the pile of paper is placed on the table a the table is depressed until the tube 61 touches the bottom of the tube and the spring 01 is compressed. The table is maintained in this position by the griping-pieces c 0 on the lever b holding down the rod (1. As the cam 3 rotates it raises the lever b, and with it the rod d, which is firmly held by the pieces 0 0 until the'piece' 0 comes in contact with the head of the adjustable screw (1 when the gripe of the piece 0 on the rod dis released, and the table continues to rise by the action of the spring until the top sheet of the pile is pressed against the stops a The lowering of the table is effected by the dropping of the lever b, which allows the griping-pieces 0 to again take hold of the rod d and draw it down. When the table is in the raised position the application of gum or other adhesive substance to portions of the sheet of paper takes place. The adhesive material is containedin two reservoirs, c and f, mounted respectively on sliding bars 6 and f each reservoir being provided with a roller, 6 to transfer the adhesive material to the paper. A to-and-fro motion is communicated to the bars 6 and f 5 by a series of levers actuated by a grooved cam, 2, mounted on the driving-shaft A. A rock-lever, e, pivoted at e to the main frame, is provided at its lower end with a bowl, 6 which takes into the groove of the cam 2. The upper end of the lever has a slot, into which takes a stud, e fixed to the bare A second rock-lever, f, pivoted atf, is connected at its lower end with the lever c by the rodf' and at its upper end is provided with a slot to receive a stud fixed to the barf (See Fig. 2.) By this arrangement the reservoirs will be moved in opposite directions, and will, by means of the rollers 0, supply the adhesive material to the paper on the parts marked D and E, Fig. 6. The paper is now taken up by the pneumatic apparatus, and is placed on a movable table, I, which is open in the center and is brought forward to receive it. This table is carried on one end of a rectangular frame bolted to the cross-pieces h, which slide in guides h in the main frame. The forward movement of the frame and table is effected in the following manner: A crank, g, terminating in a bowl, g, works in a vertical rectangular frame, I), which is provided with a socket, g Into this socket screws a rod, 9 which is supported in a guide, 9 and is connected by a rod, 9 to a rock-lever, g pivoted at g to the main frame. The head g of this rock-lever is connected by the rod g to the frame it at 9 The pneumatic apparatus consists of a tube, m, connected by means of an india-rubber tube, m, with an exhauster, m which is operated by a cam, 8, on the main shaft A. The tube at is provided with three months, m, m, and m, to take up the sheet of paper, and it is raised so as to bring the paper onto the mov able table 1, (where the paper is to be placed between guides l P, see Figs. 3, 12, and 13,)

by an arrangement of levers consisting of a three-armed lever, m m m and a bell-crank lever, m mounted on the axle in m which have their hearings in bracket-arms on' the main frame. These levers are coupled together by the link-rod m and are connected by the link-rod m to the sliding frame h at If.

The use of tubes can be limited to the ris ing of the sheet of paper, and the course of the movable table prolonged under the sheet, which will be placed without any movement of the pneumatic apparatus.

The paper is held down on the table during the return movement of the frame it by a finger, a, pivoted to the frame, and pressed against the paper by a spring, a. This fin ger is raised at the proper time by striking against a iixed stop, n (See Fig.12.) During this backward movement of the frame the paper receives on its side F (see Fig. 6) some adhesive material from the toothed roller 0 of a 1GSGlV0ll,.0 containing such mate rial, and secured to the traverse G in any convenient manner, so as to allow of vertical mo- "are square, is fired to the main frame of the machine, and is pierced with holes. On two of its vertical sides a triangular-shaped rib, intended to mark a fold on either side of the paper, is provided. A block or plate mounted on the upper end of. a rod, surrounded by a helical spring,p and inclosed in ahollow rod,

o )3 mounted in the socketuide is caused 5 7 a 1 to rise, as hereinafter to be explained, through the opening in the table 1, against the under side of the mold P, and thus hold the sheet of paper firmly against the mold, the plate or block being maintained in position by the spring 12 The hollow rod 12 passes through the socket-guidep, and is connectedat 19 to a lever, p, which is pivotedat 1) to the frame. The lever 12 rests on and receives vertical motion from a cam, 41., mounted on the main shaft A. The hollow rod 11 (see Fig. 11) carries at its upper end. a cross-head, 19 to which are attached, by rivets or screws, flat springs 19 which carry the bearings forthe axle of two rollers, 19 and 19. These rollers have each a rib or feather thereon, and are so arranged that as they rise by the action of the cam 4 on the lever 19 they are caused to push up and press the paper against the vertical sides of the mold l. The axles of these rollers carry small pinions, which gear with a rack suitably placed for the purpose, and by which rotary motion is communicated to the rollers as they rise and fall. The rollers havin g by this time arrived at the top of the mold P, the ribs or feathers thereon come into play and bend inward first the plain side. and then the gummed side of the paper projecting above the top of the mold, as seen best at Fig. 11. At the same time a fixed vertical blade. or finger,

1), (see Fig. 1,) secured in front of the crosshead f, is raised and presses up one end of the blank against the end of the mold, and thus forms the first fold in the bottom of the bag.

Following the action of the pressing-rollers 12 p is that of a top presser, which completes the folding down of the blank and the joining of the gummed folds to form the top side of the This top presser is composed of several parts, which are mounted 011 a projecting arm, q adiustably affixed to a vertical rod, g (see Figs. 1, 2, and 11,) suitably connected with alever, (1. This lever q is pivoted at q to the upper end of a vertical staiut ard, q and is maintained in contactwith a cam, 7,011 the main shaft A by a spring, (1 or analogous device. As this cam 7 rotates, the lever will be depressed, and downward motion will thus be communicated to the top presser. The parts which compose this presser are, first. a horizontal blade or plate, g which presses down one-say the left-side of the paper; secondly, a horizontal blade or plate, q, to pressdown theother or right side ofthepaper on the top of the left side thirdly, a block covered with india-rubber, q', which presses on thetwo folded sides and holds them togethersufliciently long for the adhesive substance on the right side to set; and, fourthly, a vertical finger, q, fixed to the projecting arm g, which forms the second fold in the bottom of the bag. The blades or plates g and g are fixed to square rods g and g", which are capable of sliding vertically in the projecting arm q, and

are prevented from dropping from the pro- I jecting arm by nuts screwed onto their heads.

The rod (1" is somewhat longer than the rod q, in order that the two blades (1 and q shall come. into action consecutively. The block q is mounted on a rod, 11 which is also capable of sliding vertically in the projecting-arm qt, and is provided, like the rods, with a screwnut. The rod q is surrounded by a coiled spring, (1 (see Fig. 1,) whichis compressed when the block rests onto the top of the bag, and bears with a certain amount of pressure on the folded-over sides of the bag. The continued movement of the cam 4: will cause the lever 19 to descend and allow the pressing-roll ers 1f 19, with their accessories, to descend by their own weightinto the position shown at Fig. 3. The cam 7 will raise the arm q, and

with it the finger q, preparatory to the completion of the bottom of the bag by a special apparatus, while the horizontal blades g and g and the block (1" are allowed to remain in contact for a short time with the paper, the first by reason of their own weight and the second by reason of the spring q,

The apparatus for completing the bottom of the bag is arranged in a horizontal plane, and is carried by the movable frame h, the movement of which it follows. In Figs. 1, 7, and 8 this apparatus is shown in its extreme rear position-viz., in repose--and in Figs. 3 and 9 it is represented in its forward position and completing the bag. It is composed of a supporting-socket, r, formed on the back of the movable frame h. This socket is intended to receive one end of a rod or bar, 0", which is secured therein by a pin or in any other convenient manner. This rod or bar 1 carries a helical spring, r coiled around it, a sockethead, 1, supporting a cross-frame, W, and at its outer end a square block, W, to which is fitted a block of iiulia-rubber, v The crossframe r carries at either end a vertical rod, on which are mounted the rock-levers W W and bell-crank levers r 1" The rock-levers r are pivoted at the point r 1, and are provided at their outer ends with springs r. The inner ends of these rock-levers W are connected to and carry between them a light flat spring, 1", which is bent into a circular form, the ends bein g connected together. The bell-crank levers 1, which have one arm counterweighted, rock on centers 1' 1' and are connected by rods r to rocking fingers r pivoted to brackets projecting horizontally from the cross-frame 1. These levers r are also connected to long rods r' which pass through openings in the curved brackets 4". These rods 1" are threaded at their ends to receive nuts T", which, on striking against the brackets r as the frame h advances, cause the levers r to be pulled back, and thus rock the fingers r on their fulcrumpins and cause them to fold in the two sides of the bag previous to the arrival of the indiarubber biock r which presses them firmly together until the adhesive material with which the edges of the paper are coated is set. The apparatus, as it retires, draws the completed bag (by the two springs 0"", see Fig. 9, which take hold of it near the bottom fold) off the mold P, and holds it over a box, S, Fig. 1, which is open at the top and rear end. At this moment the inner ends of the rock-levers r strike against ta-ppets r r fixed to the curved brackets r r and are thereby forced inward, compressing the circular spring into the oval form, (seeFig.7,)and the outer ends oftheselevers are thus opened and the bag is released from the springs r r and allowed to fall into the box S, which is raised to receive it. The bag may be held in the box in any suitable manner while the box S is being in verted,in order to deposit the bag with its gum med side downward on a small movable table, if, underneath. The box S is carried by a pinion, S, which is mounted on a stud-axle, S*, and, projecting from the movable frame 8, gears into a'toothed rack, S fixed at S to a table, T. The frame 8 is mounted on the rods 8, and is capable of being slid vertically in the guides 8' fixed to the frame B. Upon vertical motion being communicated to the frame 8 througha series of levers from a cam, 1, Figs. 1 and 2, on the main shaft A, the pinion S, carrying the box S, will be caused to rotate on its axis first in one direction and then in the other, according to the direction in which the frame 5 is moviug,byreason of the pinion S gearing into the fixed rack S The cam 1, during its motion,

rocks a lever, s, which ispivoted at s to the main fra1ne,a'nd connected byan adjustable rod, 8 to the short pendent arm of a three-linked rock-lever, .9 mounted on the rock-shafts. The longer arms of this lever s take into slots 8 in the pieces 5-, Figs. 1 and 10, which form part of the frame 8 and thus the rockingof the lever 8 on its axis will raise and lower the frame 8 The table 25, on which the bagis now placed, is mounted on and slides in guides in a fixed table, T, (see Fig. 4,) carried by the pillars t t. Reciprocatory motion is communicated to this table t by means ofa bell-cran k lever, t pivoted at t and worked byacam, 5, on the main shaft A, the end of the lever opposite to the cam taking into a slotted bracket, i pendent from the table it. While on the table the bag is to be rolled flat for convenience of packing. This is effected by a roller, a, carrying a fixed blade, a and mounted in slots in a pair of levers, u u, pivoted atu a to the'fixed table T. As the bag, however, is to be flattened from its mouth toward the bottom, the roller u, being in rear of the bag, must first be raised to allow the bag to pass under it to bringit into the proper position for the flattening operation: This movement is effected in the following manner: The axle of the roller projects be: yond the slots in the levers a u onto a pair of brackets bolted to and pendent from the frame h, with which they move, and having inclined parts a and horizontal parts a. As the brackets are moved forward the roller will move with them, so as to bring the blade 20 attached thereto against the adjustable stops a on the levers u. The rotation of the roller is caused by a cord and weight, a". When the axle of the roller (having passed the sprin gc- .tch a arrives at the ends of the slots in the levers u, the continued forward movement of the brackets will cause it to rise up the inclined planes and to move along the hori zontal parts a into the position shown at Fi 3. At this point the roller is allowed a moment of repose, during which time the bag is carried to the end of the fixed table T, so that the mouth of the bag shall correspond to a vertical line drawn through the axle of roller a, Fig. 3. The return movement of the frame h, with which the brackets are connected, will now commence. During this movement the bottom of the incline u the continued backward movement of the brackets will cause a cam, a keyed on the axle of the roller, to strike against a shoulder, T, (see Fig. 4,) on the fixed frame '1. The action of this cam will raise the catch a and rotate the roller so as to bring the blade n fiat onto the bag, (see Fig. 3, Sheet 11,) and at the same time wind up the cord at. The bottom of the bag is now folded down by a vertical blade or plate folder,

'12, provided with centers, .on which it turns,

and actuated by a tail-piece, c fixed to and following the movement of the pendent brackets, (see Fig. 3,) and which strikes against a projecting piece, a on one side of the blade or plate. The plate '11 is drawn back into a vertical position by a spring, c,or other equivalent device. The roller a, continuing zontal plate, y, which is brought forward to its backward movement, will, by means of the blade u", push theflattened bag between two pressing-cylinders, w w, from which it passes onto anendless apron, w, to a second pair of pressing-cylinders, m 00 which are adjustable in their bear-in gs, and to which any required pressure can be given. On passing from these cylinders the bagis received upon a horireceiveit. This plate 3 is fixed to a pendent arm, mounted on the rod 9 and in its forward movement passes through a slot in. the cross-piece 3/, against which the bag, at the commencement of the return motion of the platform, strikes, and the plate being drawn from under the bag, it is allowed to drop fiat into one of the compartments of a receiver, Y. The receiverY consists of a large circular or polygonal'shaped box, of any suitable material, divided by radial partitions into any desired number of compartments, to receive the bags, as above explained. Each compartment is intended to receive a certain numberot -saytwenty-five-bags. ThereceiverY is mounted in any convenient manner on the upper end of a vertical shaft, 2, carried in bearings 3 in a bracket-frame, 4. Upon an axle, 5, carried by the frame 4, ismounted a ratchet-wheel, 6, of twenty-five teeth, and a finger, 7, a fixedpawl, 8, being provided to prevent any back movements of the ratchetwheel 6. Keyed upon an axle, 9, carried in suitable bearin gs in' the frame 4, is a ratchetwheel, 10, of ten teeth, and to a lever, 12, mounted loosely on the same axle, is pivoted at 13 a connterweighted pawl, 11. This lever 12 is kept down in its normal position on a bar or stop, 14, by a weight, 15. On the axle 9 is keyed also a bevel-wheel, 16, which gears into a similar wheel keyed on the vertical shaft 2.

A counterweighted pawl, 18, in gear with the ratchet-wheel 6, and carried by a collar, 19, fixed and moving with the rod communicates movement to the counting apparatus as follows, viz: Every backward motion of the rod 9 will move the ratchet-wheel 6 one tooth, and once in every rotation of the ratchet-wheel the finger 7 comes into contact with the lever or arm 14, which is gradually raised into the dotted position, Fig. 1. At this point the lever escapes from the finger 7 and is caused to fall to its normal position by the weight 15, bringing with it the pawl 13, which, acting on one of the teeth of the ratchet-wheel 10, moves the latter on one tooth. The bevel-wheel 16, being keyed on the axle 9 with the ratchetwheel 6, is caused to partially rotate, and it communicates like motion, through the bevelwheel 17, keyed on the vertical shaft 2, to the receiver Y, which is thus caused to rotate such part of a circle as to bring an empty compartment opposite the cylinders 00 .10 One bag is completed and delivered from these cylinders at every backward stroke of the rod g Now, as every stroke of this rod moves the ratchet- Wheel forward, one tooth, and as one rotation of the ratchet-wheel must be made before any movement of the receiver can take place, it will be evident that the number of teeth on the ratchet-wheel 6 will determine the number of bags which shall be allowed to fall into any one compartment, y, of the receiver Y, and this number multiplied by the number of the compartments will give the total number of the bags made in the machine during one rotation of the receiver Y.

The pile of bags taken from each. compartment may be tied up separately, and thus packets of any desired number (according to the number of teeth of the ratchetwheel 6) can be made up.

The number of bags at one time in course of manufacture is four. Thus, one, a, is being folded round the mold P; a second, a, is in the box S; a third, z is on the endless tapes a0, and a fourth, 2 is in the receiver Y, and at ,the same time a sheet of paper is being supplied with adhesive material on the table a.

This machine is intended to make the bags all of one size and from sheets of paper previouslycut to the required dimensions; but by changing certain of the parts bags of a larger size can be made. The paper may also be IIO supplied from a roll suitably placed, and the requisite amount to form a bag may he cut off antom atically.

It will be evident that the various arrangements of levers for communicating motion from the cams on the main shaft A 'to the various parts can be considerably varied.

Having now described the nature of my invention and explained the manner of carrying the same into effect, I wish it to be understood that I claim- 1. The combination, in a machine for mak: ing paper bags, of a table, upon which a pile of blanks for forming bags is placed, two res-' ervoirs for adhesive substance, arranged above said table and mountedupon horizontal guides or ways, and mechanism, substantially as described, for simultaneously moving said reservoirs toward and from each other.
